# std::filesystem::temp_directory_path

From cppreference.com
< cpp‎ | filesystem

Defined in header `<filesystem>` |  |
path temp_directory_path(); | (1) | (since C++17)
path temp_directory_path( std::error_code& ec ); | (2) | (since C++17)

Returns the directory location suitable for temporary files.

### Parameters

(none)

### Return value

A directory suitable for temporary files. The path is guaranteed to exist and to be a directory. The overload that takes error_code& argument returns an empty path on error.

### Exceptions

Any overload not marked `noexcept` may throw std::bad_alloc if memory allocation fails.

1) Throws std::filesystem::filesystem_error on underlying OS API errors, constructed with path to be returned as the first path argument and the OS error code as the error code argument.
2) Sets a std::error_code& parameter to the OS API error code if an OS API call fails, and executes ec.`clear`() if no errors occur.

### Notes

On POSIX systems, the path may be the one specified in the environment variables `TMPDIR`, `TMP`, `TEMP`, `TEMPDIR`, and, if none of them are specified, the path "/tmp" is returned.

On Windows systems, the path is typically the one returned by `GetTempPath`.

### Example

Run this code

    #include <filesystem>
    #include <iostream>
    namespace fs = std::filesystem;

    int main()
    {
        std::cout << "Temp directory is " << fs::temp_directory_path() << '\n';
    }

Possible output:

    Temp directory is "C:\Windows\TEMP\"
